Soy Candles

Soy Wax was invented by a gathering of undergrads at Purdue University in the year 1996. The undergraduates needed to utilize renewable materials to develop a birthday candle, so they opted for soybean oil. Thus, in their efforts, these students found a way to transform soybean oil into a solid-state. This invention won as the 1st great invention in the students’ competition that was sponsored by two departments, which were the Purdue’s Department of Agronomy and Indiana Soybean Development Council. We discuss more soy wax and candles in this post.

What is Soy Wax

Soy wax is manufactured through the complete hydrogenation of oil sourced from soybeans. The hydrogenation process gives a triglyceride which contains a great extent of stearic acid. Soy wax is normally gentler than paraffin wax and with a melting point that is much lower, in a majority of the cases when it is mixed with other substances. However, when elements are added to it, it increases to its melting point. The lowered melting point ranges from 49 to 82 degrees Celsius contingent upon the blend. The thickness of soy wax is about 90% than that of water or 0.9 g/ml. This implies 144 oz (9 pounds of wax can fill almost ten containers of 16-oz each (160 liquid ounces).

Soy wax is accessible in piece and pellet structure and has a grayish, misty appearance. Its lower dissolving temperature can imply that candles will liquefy in a hot climate. Since soy wax can typically get utilized in compartment candles, this isn’t a lot of an issue.

Choosing the best soy wax

  • For most customers, the most significant element of a candle is the aroma. The quality of a candle’s fragrance when it is being consumed by fire alluded to as the scent toss and how well it occupies a space relies upon a few factors, including the kind of wax.
  • Getting a solid scent toss with soy can be a little more challenging than with paraffin, yet it’s entirely feasible when you start with an incredible wax.
  • The obscure, semi-matte finishing of soy candles is quite appealing to most customers. While soy is known for frequently having a rough or cratered surface after it is completely burnt, it is completely different from the smooth post-burnt surface of paraffin. This can be an advantage to the individuals who need to be certain they are consuming a product that has been manufactured from natural raw materials.
  • Another component of soy wax to note is how it adheres quite fast to the walls of the containers in which it is packed while it has solidified. This means that you only need glass adhesion when you are using transparent containers.


Another significant component of soy was its frosting. The term frosting refers to the small crystals that form at the top and the sides of the wax. Over time, all soy waxes form frosting when they are used. The frosting, however, does not influence the performance or the functioning of the candle. However, some wax tends to be less prone to exhibiting frosting than their counterparts.
